Quantitative and Qualitative Fit Testing

May 12, 2015

Fit testing is an integral part of any respiratory protection program. Performing a fit test prior to the use of a respirator is required by Cal/OSHA Standard 5144 – Respiratory Protection. The process of conducting a fit test not only evaluates the user’s ability to correctly don a respirator, but it also verifies the proper fit of the respirator as the size of the respirator varies by manufacturer. Qualitative or quantitative fit tests can be performed.

Qualitative fit tests (QLFT):

Bitrex

Irritant Smoke

Saccharin

Quantitative Fit Testing (QNFT):

Portacount

Many respirators can be tested including:

Full-face masks

Half-face masks

Dust masks (N95, P100, N100)

Supplied air respirators
